This paper offers a brief overview of the historical implications of residential segregation in Busan, Korea. It first reviews the history of residence from the early 1900s to the present and the transition of residential boundary of the City of Busan. It then considers the characteristics of residential segregation and the important factors in it. The social class of pre-industrial society led the inequality of residential areas around the Eubchee. The existed Korean residential areas were separated by newly built-up residential areas in the Japanese colonial era. After the liberation from Japanese Rule and Korean War, rapid population growth made considerable slums across the City of Busan. These slums were an important factor to segregate residential areas from prosperous areas ever afterward. The socio-economic status has related to residential segregation through the formation of differential housing classes since 1990s. The historial analysis of these periods will offer an insight into how the dominant factors lead residential segregation in a specific period by promoting a more socio-economically integrated society.

The purpose of the study was to identify the mediating effects of self-efficacy between job-stress and depression in regional hospitals' workers. The data of this study were collected from 700 hospitals' workers who have been working in 306 hospitals in B city. And the data were collected from Feb. to May 2012. To determine the impact of self-efficacy on job-stress and depression for men and women workers in local hospitals, we measure self-efficacy, job-stress and depression of workers and analyze their relationships. There was a negative relationship between self-efficacy and job-stress(r=-.238, p<.001), depression(r=-.626 p<.001). Verifying the mediating effects of self-efficacy to the impact of job stress on depression, the mediating effects of self-efficacy were significant. It suggests that there is a need to relax the negative impact of job stress through the promotion of self-efficacy for individual or team-level organization.

The purpose of this study is to find and compare the differences in stress level, stressor, and coping style of high school students according to their personality traits. And to identify the personality traits contributing to stress reduction. The results of the study can be used as basic data for reducing the stress of adolescents to improve their academic achievement and maintain mental and physical stability. The questionnaire survey was conducted for 10 days from June 7 to June 16, 2017 for S high school students in Chungbuk Province. The study employed four measuring instruments as Ego-gram, Ok-gram, stressor scale, and stress coping type scale. Individual personality traits were classified into ego-states and ok-states in TA (Transactional Analysis). Stressors are classified into 5 categories (school life, home life, human relationship, myself, environment) and stress coping styles are classified into 4 categories (problem-focused coping, social-support coping, feeling-focused coping, hope-thinking coping) used in the previous studies. The collected data were analyzed using T-test, ANOVA, and multiple regression analysis. As a result, the stress level of high school students showed significant differences according to sex, year, grade, sleeping time, personality traits, and coping styles. Personality traits that contributed to the stress increase were NP, AC, 'you positive', 'i negative' and personality trait that contributes to stress reduction is 'you negative.' Therefore, we can judge that individual personality traits have significant effects on stress level, stressor, and coping style and need to find the effective stress management method suitable for individual personality traits using counseling, repetition training, self-suggestion etc.

This study was performed to analize the possibility of validation about Questionaire of Sasang constitution Classification which has been made through several stages for the purpose of promoting the objectivity of Sasang constitutional classification. The results of statistical research about the responses data of Sasang Questionaire are as follow: 1. In the case of mutual relation between the items of the QSCC(Questionaire of Sasang Constitution Classification) and 16PF, every item displaced singnificant result.(in male group) 2. In the investigation to classify the score distribution of Sasang items three groups and analize the gap of mean value in each of 16PF, the characters of each Sasang group were turn out as follows: (1) The Taee-Yang group has extrovert and narcissistic inclination. (2) The So-Yang group shows remarkable extrovert inclination. (3) The Tae-Eum group has hidden fear and introvert inclination. (4) The So-Eum group has revealed physical unstability and introvert inclination. 3. The statistical research of female group didn't display any significant result. It will be necessary to analize the respondent shape of female group and introduce new items to coincident with faminine psychology. 4. In the research using 16PF accompany with QSCC in order to classify the Sasang constitution, the accuracy rate of diagnosis showed inspiring elevation. For that reason, it seems to be desirable to introduce some items of 16PF into QSCC. According to above results, although QSCC contains several problems to be solved, its validity was proved, and the analysis of statistics suggests the possibility to step forward by introducing 16PF in some problems of promoting the accuracy of Sasang Constitutional diagnosis, assuring the objectibity of Sasang constitution classification and so on.

Mid-life is a period of transition and crisis in human development. A multidimensional approach is needed to understand the meaning of the mid-life crisis. In order to understand the crisis of middle age, it is required to understand the psychological aspects of individuals, behavioral and social aspects. Jung referred to the middle age as the period of individuation. In other words, it is a process of stabilizing and integrating several individuals with fragmented personalities. The discovery of the meaning in life in middle age relates to the meaning of existence and to become a true community member through understanding of others and oneself. The sense of crisis in middle age has a deep correlation with the meaning in life, and the sense of crisis in middle age can be lowered through the meaning of life. However, in the process of discovering the meaning in life, adaptation to family and social crises and coping with stress will be important factors.

To clarify the phytoplankton blooms in Lake Shihwa after the construction of a dyke, a study on the environmental factors, the distribution of chlorophyll-a, phytoplankton standing stocks, dominant species and primary productivity was carried out in Lake Shihwa and adjacent coastal areas from October, 1995 to August, 1996. Lake Shihwa is brackish water with mixing of freshwater from tributaries and the remaining salt water at the bottom. The dense phytoplankton bloom of average value of 168.6 ${\mu}gChl-a\;l^{-1}$ have occurred throughout the year in Lake Shihwa which is eutrophicated by the large input of nutrients from inflowing 5 tributaries and Shihwa Industrial Complex. The major organisms of algal bloom in Lake Shihwa were diatoms, Cyclotella atomus, Nitzschia sp. and Chaetoceros sp. in autumn and winter, and dinoflagellate Prorocentrum minimum and Chrysophyceae in spring and summer. The autumn and winter diatom blooms were limited by the depletion of silicate in the lake. Diatom blooms have occurred in the coastal areas adjacent to Shihwa lake from winter to summer due to the inflow of nutrient rich-water from Lake Shihwa. The primary productivities in the Lake Shihwa ranged from 2,653 mgC $m^{-2}\;day^{-1}$ to 9,505 mgC $m^{-2}\;day^{-1}$ with an average of 3,972 mgC $m^{-2}\;day^{-1}$. However, most of the high primary production was limited to the shallow euphotic zone due to the inhibition of light penetration. The primary productivities during autumn and winter were limited by the depletion of silicate. Lack of photosynthesis and the decomposition of falling organic matter under the middle of water column accelerated the depletion of dissolved oxygen in the bottom layer.
